Patented Dec. 22, 1936 UNITED STATES PATENT OFFICE 1 Claim The present invention relates to new and useful improvements in guy Wire fasteners particularly for telephone, telegraph or electric light poles, etc., although it will be understood, of course, that the device may be used for any purpose for which it may be found adapted and desirable.

The primary object of the invention is to provide, in a manner as hereinafter set forth, a fastener of the aforementioned character embodying novel means through the medium of which a guy wire or the like may be securely fastened without the usual clamps, bolts, etc., the construction and arrangement being such that the grip on the guy wire or the like will be increased as the pull is increased.

Another very important object of the invention is to provide a fastener of the character described in which the guy wire or the like may be expeditiously engaged with a minimum of labor.

Other objects of the invention are to provide a guy wire fastener which will be comparatively simple in construction, strong, durable, highly efficient and reliable in use, compact and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views and wherein:-

Figure 1 is a view in front elevation of the invention, showing a guy wire clamped therein.

Figure 2 is a view in side elevation of the device.

Figure 3 is a cross sectional view, taken substantially on the line 3--3 of Figure 1.

Figure 4 is a vertical sectional view through the invention, taken substantially on the line 4-4 of Figure 2.

Figure 5 is a view in front elevation, showing the device before the guy wire has been clamped therein, the pull bars being broken away.

Referring now to the drawings in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a substantially ovate plate I of suitable metal having formed therein a longitudinal slot 2. Formed in the periphery of the plate I is a groove 3 for the reception of a guy wire or the like 4. As best seen in Figure 2 of the drawings, the groove 3 is spirally ribbed for a better grip on the guy wire 4. Also formed in the periphery of the plate I, at intermediate points, are arcuate recesses 5.

The reference numeral 6 designates a pin which is adapted to travel in the slot 2. Journalled on the pin 6 are what may be referred 5 to as pull bars l having openings 8 in their free end portions. Also pivotally mounted on the pin 6 are diverging pairs of links 9 between the free end portions of which grooved rollers I0 are journalled. The rollers I0 are adapted to press 10 the guy wire 4 into the recesses 5.

The reference numeral II designates a pair of elongated plates which extend transversely across the small end portion of the plate I and between the end portions of which grooved rollers 15 I2 are journalled. Pairs of links I3 have one end pivotally connected to the plates II and their other ends pivotally connected to the outer end portions of the links 9.

t is thought that the operation of the device 20 will be readily apparent from a consideration of the foregoing. To engage the guy wire 4 in the fastener, the pin 5 is pushed upwardly or forwardly in the slot 2 in a manner to expand the rollers I0, as clearly shown in Figure 5 of the 25 drawings, and move the rollers I2 away from the small end of the plate I. The guy wire 4 may then be conveniently inserted between the rollers I2 and I0 on one side of the plate I, brought around the large end of said plate and then inserted between the rollers I0 and I2 and the plate on the other side of said plate. The bars l are then pulled in a manner to move the pin 6 downwardly or rearwardly in the slot 2, thereby swinging the rollers I0 inwardly for 35 clamping the guy wire 4 tightly in the recesses 5 while at the same time shifting the rollers I2 toward the plate I for gripping the guy wire therebetween. This is shown to advantage in Figure 4 of the drawings. It will thus be seen 40 that the guy wire will be securely fastened and it will further be noted that the greater the pull that is exerted the tighter the guy wire will be gripped. The reference numeral I4 designates pins which connect the links 9 and I3 and on which the rollers I0 are journalled and the reference numeral I5 designates pins which connect said links I3 and the plates II and on which the rollers I2 are journalled.

It is believed that the many advantages of a- 50 fastening device constructed in accordance with the present invention will be readily understood and although a preferred embodiment of said device is as illustrated and described, it is to be understood that changes in the details of con- 55 struction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is:

A fastener of the class described comprising a substantially ovate plate having a peripheral groove therein for the reception of a guy wire, said plate further having substantially arcuate recesses therein at an intermediate point, said plates still further having alongitudinal slot therein, a pin operable in the slot, pull bars pivotally connected to said pin, pairs of diverging links pivotally connected to the pin, grooved gripping rollers journalled between the outer portions of the second named plates and at 10 their other ends to the .outer end portions of the rst named links.
